Your Guide to Sustainable Building and Renovation.
The demand for photovoltaic systems for single-family homes and new construction projects continues to grow steadily. For developers, the key question is: What funding opportunities are currently available – and how can they be used most effectively?
As an architectural practice, we support you in the strategic planning and integration of PV systems – including guidance on suitable funding programs offered by KfW.
The Most Important KfW Funding for Photovoltaics
KfW 270 – Renewable Energy Standard
The program KfW 270 KfW 270 is the primary funding scheme for private developers in the field of photovoltaics.
What is funded?
– Photovoltaic systems (roof and façade)
– Electricity storage systems (battery systems)
– Planning, assembly, and installation
Your benefits:
– Financing of up to 100% of investment costs 100 % of the investment costs
– Attractive interest rates and flexible repayment terms and flexible terms
- Can be combined with regional funding programs
Particularly suitable for:
New construction projects with integrated PV systems
– Retrofitting existing buildings
– Energy-efficient renovations
Important: The funding application must be submitted before the start of any construction or installation work.
Funding in the Context of New Construction and Renovation
KfW 261 & Climate-Friendly New Construction (KFN)
If you are planning or renovating your building as an efficiency house, you can benefit from additional funding.
KfW 261 (Renovation):
– Subsidized loan with repayment grant
– PV systems as part of a holistic energy concept
Climate-Friendly New Construction (KFN):
– Funding for energy-efficient new buildings
– Photovoltaics are often required to meet the standard
-> Advantage:
You can combine funding for both the building and the PV system within an integrated
concept.
Additional Benefits Beyond KfW Funding
In addition to KfW programs, developers benefit from further financial advantages:
– 0% VAT on photovoltaic systems
– Tax exemptions for many private PV systems
– Feed-in tariffs under the Renewable Energy Sources Act (EEG)
– Regional funding programs (e.g. Baden-Württemberg)
-> This combination makes photovoltaics particularly economical today.
Our Recommendation as an Architectural Practice
Maximum economic efficiency is not achieved through isolated measures, but through holistic planning::
– Early integration of PV systems into the design
– Coordination of roof shape, orientation, and technology
– Combination with heat pumps and storage systems
– Use of optimal funding structures
-> This is exactly where we come in: we support you from initial design through to funding strategy..
Conclusion: Make Targeted Use of Funding
For developers in 2026:
– KfW 270 is the key funding program for photovoltaics
– Additional programs apply for efficiency house standards Energy efficiency house standards
– Success lies in the right combination of all funding components
